BMW M4 Replacement Engines

The BMW M4 is a high-performance sports coupe that embodies BMW’s motorsport heritage with cutting-edge technology and aggressive styling. First introduced in 2014 (F82), the M4 replaced the M3 Coupe, offering a more refined yet exhilarating driving experience. Over the years, it evolved into the M4 Competition (2016–present) and the track-focused M4 CSL (2022–present), delivering increased power and sharper handling. The latest G82 generation (2021–present) features a bold design, improved aerodynamics, and a powerful twin-turbocharged inline-six engine. With trims like the M4 Competition and M4 CSL, the M4 remains one of BMW’s most thrilling performance models.
